WebJan 23, 2024 · The test statistic is the F statistic for ANOVA, F=MSB/MSE. Step 3. Set up decision rule. The appropriate critical value can be found in a table of probabilities for the F distribution(see "Other Resources"). In order to determine the critical value of F we need degrees of freedom, df 1 =k-1 and df 2 =N-k. In this example, df 1 =k-1=4-1=3 and ... WebFor Welch's ANOVA, Minitab uses the degrees of freedom for the denominator to calculate the probability of obtaining an F value that is at least as extreme as the observed F value. Interpretation. Minitab uses the F-value to calculate the p-value. Typically, you should assess the p-value because it is easier to interpret.
